  • Detail-aware uncalibrated photometric stereo 

    Agudo Martínez, Antonio (2023)
    Conference report
    Open Access
    Photometric stereo is the problem of jointly inferring the 3D reconstruction, reflectance, lighting and specularities of an object from a set of visual signals. Recently, some variational, uncalibrated, unsupervised and ...
  • Grasp-oriented fine-grained cloth segmentation without real supervision 

    Ruijie, Ren; Rajesh, Mohit Gurnani; Sánchez Riera, Jordi; López Rodríguez, Andrian; Zhang, Fan; Tian, Yurun; Alenyà Ribas, Guillem; Agudo Martínez, Antonio; Demiris, Yiannis; Mikolajczyk, Krystian; Moreno-Noguer, Francesc (Association for Computing Machinery (ACM), 2023)
    Conference report
    Open Access
    Automatically detecting graspable regions from a single depth image is a key ingredient in cloth manipulation. The large variability of cloth deformations has motivated most of the current approaches to focus on identifying ...
  • COmparative study of feature localization methods for endoscopy image matching 

    Urdapilleta Martín, Ana; Agudo Martínez, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    The purpose of this work is to determine which is the best general method of feature localization for image matching in endoscopy images. To accomplish this, we conduct an exhaustive analysis of ten well-known feature ...
  • PoseFix: correcting 3D human poses with natural language 

    Delmas, Ginger; Weinzaepfel, Philippe; Moreno-Noguer, Francesc; Rogez, Grégory (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    Automatically producing instructions to modify one’s posture could open the door to endless applications, such as personalized coaching and in-home physical therapy. Tackling the reverse problem (i.e., refining a 3D pose ...
  • Introducing social robots to assess frailty in older adults 

    Civit Bertran, Aniol; Andriella, Antonio; Barrué Subirana, Cristian; Antonio, Maite; Boqué, Concepción; Alenyà Ribas, Guillem (2024)
    Conference lecture
    Open Access
    Frailty is a crucial indicator in determining the well-being of older adults in terms of their health. With the growing number of elderly people, the demand for geriatricians is increasing, which means that they have less ...
  • Adaptive human-robot collaboration: evolutionary learning of action costs using an action outcome simulator 

    Izquierdo Badiola, Silvia; Alenyà Ribas, Guillem; Rizzo, Carlos (2023)
    Conference report
    Open Access
    One of the main challenges for successful human- robot collaborative applications lies in adapting the plan to the human agent’s changing state and preferences. A promising solution is to bridge the gap between agent ...
  • Heteroscedastic Gaussian processes and random features: scalable motion primitives with guarantees 

    Caldarelli, Edoardo; Chatalic, Antoine; Colomé Figueras, Adrià; Rosasco, Lorenzo; Torras, Carme (Proceedings of Machine Learning Research (PMLR), 2023)
    Conference report
    Open Access
    Heteroscedastic Gaussian processes (HGPs) are kernel-based, non-parametric models that can be used to infer nonlinear functions with time-varying noise. In robotics, they can be employed for learning from demonstration as ...
  • Morse cell decomposition and parametrization of surfaces from point clouds 

    Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro, Franco; Torras, Carme; Verdaguer López, Miquel (Publicacions de la Universitat Jaume I, 2022)
    Conference report
    Open Access
    An algorithm for the reconstruction of a surface from a point sample is presented. It proceeds directly from the point-cloud to obtain a cellular decomposition of the surface derived from a Morse function. No intermediate ...
  • A comparison between model-based and data-driven leak localization methods 

    Romero Ben, Luis; Blesa Izquierdo, Joaquim; Cembrano Gennari, Gabriela; Puig Cayuela, Vicenç (2023)
    Conference report
    Open Access
    Water networks are crucial infrastructures for the sustainability of modern cities, and hence their proper operation is of great importance. This includes the fast detection, localization and repair of leaks, which may ...
  • Quadratic dynamic matrix control for fast cloth manipulation 

    Caldarelli, Edoardo; Colomé Figueras, Adrià; Ocampo-Martínez, Carlos; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    Robotic cloth manipulation is an increasingly relevant area of research, challenging classic control algorithms due to the deformable nature of cloth. While it is possible to apply linear model predictive control to make ...
  • Teaching a robot where doors and drawers are and how to handle them 

    Cupec, Robert; Vidovic, Ivan; Šimundic, Valentin; Pejic, P.; Foix Salmerón, Sergi; Alenyà Ribas, Guillem (2023)
    Conference report
    Open Access
    We address the problem of teaching a service robot to detect doors and drawers in indoor environments. We propose a robust and accurate method in which a human demonstrates to the robot how to open doors and drawers that ...
  • Gestión de energía, mediante control predictivo, de un vehículo de pila de combustible 

    RUIZ SICILIA, ÁLVARO; Escachx Estévez, Bryan; Costa Castelló, Ramon (2023)
    Conference report
    Open Access
    En este trabajo se propone el uso del Control Predictivo (MPC) para resolver el problema de la gestión de energía en un vehículo híbrido en un entorno industrial. En concreto, se propone un controlador para un sistema ...
